Thoroughly groom your beard with the Wahl Stainless Steel Advanced. This beard trimmer has a battery life of 4 hours. If your trimmer runs out of battery, you can use the quick charge function. This will let you charge the Wahl beard trimmer in 1 minute for a quick shave. Because the shaver foils are waterproof, you can immediately rinse them under the faucet after use. The trimmer comes with a wide selection of accessories and comb attachments from 2 to 25 millimeters. Shave your beard short for a professional look or groom your full beard with the longer combs. You can also groom your ears, nostrils, and sideburns with the attachments.
